Q1. Identify five (5) important items of personal safety.

1. Eye protection –spectacles/goggles, shields, visors. 2. Hands, arm & heads protection – gloves, hats.

3. What four (4) precautions should be taken when handling live air bags?

1. Adjust the Steering Wheel If there is a Feature.

1. Avoid water surface when working with electricity. Never touch or try repairing any electrical equipment or circuits with wet hands.

2. Never use equipment with frayed cords, damaged insulation or broken plugs.

Ans.

Disconnect the negative (-) cable of the battery when the ignition is off. You must first remove the air filter box of the passenger compartment.

Before removing the airbag unit, remove the electrostatic charge.

6. What is an intermittent fault?

Ans. Intermittent are usually caused by some mechanical change like
temperature, vibration, moisture and physical stress that temporarily changes

the electrical characteristics of device under test. 80% of intermittent faults are due to loose / contaminated inter-connections.

11. What could be the fault if a module does not respond to the diagnostic scan tool?

Ans. Following could be the reason Airbag module may not be communicating correctly:

Ans. Damaged clock spring in steering column is the one of primary cause, airbag unit in side steering wheel and wiring inside the wheel are the possible another cause to turn light on.

13. Customer’s vehicle has entered your workshop complaining about the radar cruise control inoperative the other week when driving from Melbourne to Sydney. Customer said that the radar cruise control worked fine before the trip and now after the trip. What could have been the cause of the fault?

17. Why should Technical Service Bulletins (TSB) be reviewed as part of your diagnosis?

Ans. So that you get to what procedure for should be followed which are issued by manufacturer for such a problem which might be not possible by general diagnosis of technician but the manufacturer have released bulletin for such issue.

ways. The first is to alert a driver to the risk through a light, a sound, or both. Second with the use of radar, lasers and cameras Vehicles with front and rear cameras also provide visual warnings of obstacles.

20. Explain the function of a pre-collision avoidance system?

Lane Departure Warning (LDW): A visual, audible, or haptic alert that a driver is crossing lane markings.

Adaptive Cruise Control: the systems use radar or lasers to adjust cruise control to maintain an appropriate distance from the vehicle in front.

22. What is an Adaptive Front Lighting System?

Ans. The Adaptive Front-lighting System optimizes distribution of light from the headlights according to driving circumstances. Depending on vehicle speed and

Ans. AFS control module performs control of the adaptive front lighting system.

Types of sensors used are:
image sensors,
Front and rear chassis sensors,
Rain sensors,
Vehicle speed sensor
25. What is the purpose of Air Bag system?

Door mounted airbags can be located in the front doors on both sides of the vehicle.

27. How does the Air Bag system operate during a crash?

Ans. This system proactively supports the driver by keeping the vehicle in the center of the lane within a full speed range. The system aims to increase comfort by supporting the driver with his lateral control task. It requires the driver to keep his hands on the steering wheel.

30. Explain how lane keeping assist operates?

32. What happens to Occupant Detection System when no one is seated in the passenger seat?

Ans.

36. Explain the operation of the Adaptive Cruise Control system?

Ans. By monitoring other vehicles and objects on the road, adaptive cruise control enables a safe and comfortable driving experience. It does so by helping the driver keep a steady vehicle speed at a given moment. The driver can set their preference regarding certain factors, such as the distance to the car in front, driving mode. Together with information about speed limits, road curvature, accidents data and more, these choices influence the automatically selected speed.

Ans. A pretensioner is designed to retract some of the webbing of a seatbelt the instant a collision occurs, tightening the seatbelt to restrain occupants quickly and reducing the amount they are thrown forward in a moderate or severe front crash.

40. Explain the purpose of the seat belt pretensioner?

The PCM energises the Actuator by providing the ground. On a Scope trace, the on time pulse is the downward Pulse. On positive-feed Circuits, where the computer is supplying the Voltage to turn a circuit on, the on-time pulse is the upward pulse. One complete Cycle is measured from one on-time pulse to the beginning of the next on-time pulse. To Test an actuator, you need to know what it basically is. Most actuators are Solenoids. The computer controls the Action of the solenoid by controlling the pulse Width of the control signal. You can see the turning on and off the solenoid by watching the control signal on the Oscilloscope. The voltage spikes are caused by the Discharge of the coil in the solenoid.

43. A poor ground in the reference voltage circuit can cause higher than normal readings at the control module?

a. True
47. Looking at Pinpoint Test A of the SRS system below, answer the following questions.

Looking at the Pinpoint Test A3, what test is being conducted and what is the specification required to pass?

48. When road testing a vehicle, at what speed does the lane keeping assist systems become active?

a. 35km/h
b. 45km/h
c. 55km/h
d. 65km/h
49. When road testing lane keeping assist, what does the green line below mean?

Words: Audible, Circuits, Diagnostic, Disable, Electrical, Fault, Lamp, Illuminate, Ignition, Inoperative, On, Safety,
System, Vehicle, Warning,
All _______________ systems can detect _______________ faults, and if found will _ Disable the system and notify the driver through a Warning lamp in the instrument cluster. Depending on circuit design, a system
_______________ may cause the warning lamp to fail to _ Illuminate _, remain lit continuously, or flash. Some systems use a tone generator that produces an Audible warning when a system fault occurs or if the warning lamp is on_.

Some warning lamp should illuminate with the __Safety ____ key on and engine off as a bulb check. If not, the _______________ module is likely to disable the _______________. If the safety system warning light remains _______________, the safety system may or may not be disabled, depending on the specific _______________ and the fault
detected. Some warning lamp _______________ have a timer that
extinguishes the _______________ after a few seconds.

Do not use a battery or AC-_ Powered voltmeter, Ohmmeter, or any other type of test equipment not Specified in the service manual to test the Air bag module. Never use a_ Test-light to probe for voltage.

57. What are the conditions that can set DTC B1610/13 Front Airbag Sensor RH Circuit Malfunction?

Ans.

1. Center airbag sensor assembly detects line short.

Ans.

1. . Instrument panel wire
2. Instrument panel wire assembly
3. Front passenger airbag assembly (Front passenger side squib) 4. Center airbag sensor assembly
